Unanswered: Are there any good alternatives to this book?
I am usually not very impressed of books that are as fundamental as the "Teach yourself" books, but there are times when they are useful and that is when you want to learn the fundamentals quickly so that you understand the philosophy of a product so that you know how to perform the fundamental setup and administration as it designed to be performed. The first and oly book I have read about Microsoft SQL Server was "Teach yourself SQL Sever 7.0 in 21 days" and since that have I been able to learn all the advanced details on my own from online documentation and own experiences.
Despite I know a lot of DB2 do I still feel that I not understand the fundamentals about how to administer it enough, but the "Teach yourself" book is now eight years old.
I wish they had a table of contents but I often agree about certification guides. At least when it comes to programming languages (I am a Java developer a lot more than I am an DB2 administrator) is a certification guide that teach about everything everyone should know and no more often the best choice.
